Course Descriptions

Algebra I provides the basis for all higher level mathematics and science courses. The content includes a review of arithmetic operations (addition, subtraction, multiplication, and division) of positive and negative numbers. The course covers the study of equations in one and two variables (unknowns represented by letters), polynomials, algebraic fractions, roots and powers, and second degree equations. Students learn to apply the material to real-life situations by solving word problems. Students learn how to apply the use of a TI83+/84+ graphing calculator in working mathematical concepts. It is truly the foundation course for all other math courses.


Geometry is the study of points, lines, planes, and the relationship of figures. Students investigate properties in synthetic, coordinate, and transformational approaches. Properties of angles and triangles are examined and used extensively. Also, studies of polygons, circles,coordinate graphing of points, linear equations, volume, and surface
area of figures are investigated.
